DCLW Decanter centrifuge is driven by two motors. The main motor drives the drum and the outer casing of differential through belts while the auxiliary motor, after the differential shifting speed, drives the spiral propeller. This will make the drum and the spiral propeller rotate in the same direction with a certain differential speed.

decanters

Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system.oilfield Decanting Centrifuge are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid.

 

Centrifuges are used to process unweighted and weighted, water-based and oil-base drilling fluids. The DCGLW series centrifuge uses high G-forces to separate fine solids from liquids.

Mud is introduced in the feed chamber through a feed tube and exits in to the bowl via four nozzles. The DCGLW is able to exert up to 2,870 G’s on the mud. It has a fixed drive unit and has customized hardware and software packages that can be designed to meet specific installation and operation needs. With a processing capacity up to 200 gal/min the 3400 series centrifuge offers outstanding performance over a wide range of drilling applications and conditions.

Deanter centrifuge is a very efficiency equipment for wasterwater process working progress. The centrifuge consists of a solid bowl, which rotates and contains the process. A screw conveyor, contained within the bowl, turns at a slightly different speed from the bowl.

DC Decanter centrifuge is an effective separation equipment which use centrifugal acceleration generated by high-speed rotation into the acceleration of gravity to shorten thousands of times of the settlement time of solid particles than in the gravity field. The solid particles are discharged from the drum through the screw conveyor continuously and without interruption.
decanter centrifuge

The material is conveyed to the screw discharge port through the feeding pipe and uniformly distributed in the drum through the spiral discharge port which is rotated at a high speed, and the main motor drives the drum to rotate at high speed through the belt to generate thousands of times of gravitational acceleration.

Rapidly settlement and accumulation of the solids particles in the inner wall of the drum, there is a relative movement of the screw conveyor to the drum, which will continuously push the sediment towards to outlet. The sediment is mostly dewatered under the combined action of the screw conveyor squeeze and drum dehydration. After the separation, the liquid is discharged freely through the liquid outlet point.

Installation and adjustment:

1. Should have the necessary space location when install the decanter and electric control panel for easy to maintain and operate.
2. The potential difference of the liquid level and inlet mouth keep in 0.3-0.5m.
3. The inlet valve should installed on the outlet of the head tank which should be close to the inlet.

5. The machine adopts elastic floating bracket, the horizontal error is 0.02mm/m when install.
6. Equipped a section of transparent tube between the inlet pipe, to observe the feeding.
7. When disassembling the drum assembly should be reliably to avoid damage the bearing. The touching surface of the spare parts must clean before install it.
8. Professional electrician installs the electric machine to ensure the accurate wiring.
9. Move the motor base plate location and adjustment the belt tightness, Tt put pressure on the belt for 3 to 5 kg, belt deflection between 10-15 mm is advisable.

DC-China leading decanting centrifuge manufacturer.

Centrifuge for is fourth phase oil drilling rig fluid solids control equipment. Mainly separate particle sized 2-7microns. Drilling fluid centrifuges have got large development on both structure and functions.

Especially there are many manufacturers design centrifuges according to drilling mud features or property. Then the centrifuge become many models and types used in various drilling projects.

Always there is a screw pump or submersible pump to feed the mud to Decanter Centrifuge. After the drilling fluids being fed into the centrifuge drum, under the function of centrifugal force, solid phase particles are pushed to the internal wall of the drum, then to the solid discharge export of the small end of the drum and excreted. While the fluids is excreted from the overflow hole of the large end.

Especially, DC Solid control combines abroad advanced technology and our unique design to developed the most cost-effective drilling fluid centrifuges. Recent years, our superior quality centrifuge and lowest line price had been recognized by more and more users.

DCLW Series Decanter Centrifuge units are supplied with advanced controls for both variable speed bowl and scroll back-drive optimization making them easily configured to produce a wide range of sludge dewatering results. DCLW Series decanters are very easy to set up while being extremely robust, stable, and reliable in everyday use, without the ease of use detracting from the quality of the operating results.

The decanter centrifuge produced by DC Solid control is available in several sizes and models to function in different kinds of organizations. Coming in a range of sizes, horizontal continuous cleaning decanter centrifuges provide an effective, low maintenance solution to liquid clarifying and solids dewatering with advanced process and mechanical performance features.

DC Machinery Decanter centrifuges are versatile and capable of adapting to varying throughput and process and material types. The machines are easy to adjust, require little operator attention, are relatively quiet and feature a small footprint.

decanter centrifuge

The decanter centrifuge’s central section consists of a rotating drum with an independently rotating screw conveyor inside. The sludge is fed via inlet pipes into the mixing chamber in the screw. This is also where polymers are added for sludge flocculation. During centrifugation, the sludge is thrown through holes in the mixing chamber out against the outer walls of the drum. The dewatered sludge is transported out through the machine by the screw conveyor, while reject water is pressed back towards the reject outlet. The water level in the drum is adjustable and the type of sludge being processed determines the appropriate level.

We also provide frequency conversion decanter, compared with similar products with low energy consumption, working speed is adjustable etc. You are welcome to contact Tangshan Dachuan Machinery to get more detailed infos, we will supply our best service for you.

Drilling fluid centrifuges have got large development on both structure and functions. Especially there are many manufacturers design centrifuges according to drilling mud features or property.

In the whole solids control system, the drilling mud decanter centrifuge is the most important solids control equipment, it is the forth stage equipment and it decides the quality of drilling fluids in a way. The first equipment is oilfield shale shaker, it is one of the most important equipment, too. The second stage equipment is desander, third equipment is desilter. Sometimes they are combined to be as one equipment—drilling mud cleaner.

DCLW means horizontal spiral type which is a normal model of decanting centrifuge. Always there is a screw pump or submersible pump to feed the mud to Decanter Centrifuge. After the drilling fluids being fed into the centrifuge drum, under the function of centrifugal force, solid phase particles are pushed to the internal wall of the drum, then to the solid discharge export of the small end of the drum and excreted. While the fluids is excreted from the overflow hole of the large end.

In essence, a centrifuge is a miniature settling pit that alloys very rapid settling of solids under controlled conditions. Though much more complicated than a hydrocyclone, centrifuges have the advantage of achieving extremely fine cut points.

Specially designed to work with virtually all kinds of drilling mud, the DCLW Series centrifuges are optimized for use with the new water/synthetics based mud types, in addition to conventional oil‐based drilling fluids.
